Differences to the A-CDM Process

At non-A-CDM airports, the CTOT is calculated based on the EOBT filed in the F-Plan. There will be no TOBT, TSAT or TTOT at non-A-CDM airports.

ATC shall make sure that traffic does not depart before the CTOT window (-5 to +10 minutes). In case of a CTOT, the pushback may be adjusted on the standard taxi time to avoid heavy delay at the holding point. 

IFR Clearance

The IFR clearance will be given as normal. In case there is no CTOT displayed in the departure list, ATC may approve start-up together with the IFR clearance. If there is a heavy CTOT delay, ATC may decide to delay the start-up approval. 

EOBT and Off-Block

Traffic with no CTOT can push back, taxi and take off at any time. At non-A-CDM airports, the EOBT will be displayed in the TOBT column (e.g. LNKWA).

CTOTs

In case of CTOTs, ATC shall always make sure that aircraft depart within the -5 to +10 minute window.

REA Message

Whenever the pilot has received a CTOT, a REA MSG can be sent to the system once the pilot has reported ready. This will lock the CTOT and allow improvement. The CTOT will never get worse when the REA MSG is set. The REA MSG can be set:

  • Setting TOBT to now
  • Left-Clicking on TSAT, CTOT or the REA column 
  • Pilot set REA himself via the VDGS website

In case a pilot is not able to depart within the CTOT, ATC shall send a new EOBT to generate a new CTOT (right click on the CTOT column).
